Abstract

An image forming apparatus includes an image forming device that forms an image on a sheet and executes predetermined image forming processing, a reception device that receives a user instruction, a sensor that acquires ambient temperature information, and at least one controller that prohibits execution of the predetermined image forming processing for a predetermined period if any of a plurality of conditions including a first condition and a second condition is satisfied, wherein the first condition is a condition that a plurality of pieces of temperature information acquired at a plurality of timings have a predetermined relationship and the second condition is a condition that a predetermined instruction is received.

First claim

What is claimed is:

1. An image forming apparatus comprising:
an image forming device configured to execute an image forming processing;
a fan;
a temperature sensor;
one or more controllers configured to
execute a condensation removal process that prohibits execution of a predetermined image forming processing and drives the fan for a predetermined period; and
a reception device configured to be able to receive, as a user instruction from a user to decide timing to start the condensation removal process, a first user instruction from the user to execute the condensation removal process when the first user instruction is received and a second user instruction from the user to execute the condensation removal when the temperature information output by the sensor satisfies a predetermined condition.

2. The image forming apparatus according to claim 1 , wherein the predetermined image forming processing is the image forming processing in which image forming based on fax data is started if the fax data is received.

3. The image forming apparatus according to claim 1 , wherein the one or more controllers stores fax data received during the predetermined period.

4. The image forming apparatus according to claim 3 , wherein the one or more controllers causes the image forming device to execute image forming based on the stored fax data if the predetermined period ends.

5. The image forming apparatus according to claim 1 , further comprising a reading device configured to read an image from a document,
wherein the predetermined image forming processing is copy processing in which image forming is performed based on the read image.

6. The image forming apparatus according to claim 1 , wherein the predetermined image forming processing is printing processing in which image forming is performed based on received print data.

7. The image forming apparatus according to claim 1 wherein the second user instruction is a user instruction to execute the condensation removal when the temperature information output by the sensor is less than or equal to a predetermined value as the predetermined condition.

8. The image forming apparatus according to claim 1 , wherein the fan is driven at a rotation speed greater than or equal to a predetermined value during the predetermined period.

9. The image forming apparatus according to claim 1 wherein the temperature information is output at a first interval when the image forming apparatus is in a first power mode, and the temperature information is output at a second interval when the image forming apparatus is in a a second power mode.

10. A method of controlling an image forming apparatus including an image forming device configured to execute an image forming processing, a fan, one or more controllers, and a temperature sensor, the method comprising:
outputting temperature information;
executing, by the one or more controllers, a condensation removal process that prohibits execution of a predetermined image forming processing and driving the fan for a predetermined period;
receiving, by a reception device, as a user instruction from a user to decide timing to start the condensation removal process, a first user instruction from the user to execute the condensation removal process when the first user instruction is received and a second user instruction from the user to execute the condensation removal when the temperature information satisfies a predetermined condition.

11. A non-transitory storage medium storing a program for causing a computer of an image forming apparatus including an image forming device configured to execute an image forming processing, a fan, one or more controllers, and a temperature sensor to execute a method, the method comprising:
outputting temperature information;
executing, by the one or more controllers, a condensation removal process that prohibits execution of a predetermined image forming processing and driving the fan for a predetermined period,
receiving, by a reception device as a user instruction from a user to decide timing to start the condensation removal process, a first user instruction from the user to execute the condensation removal process when the first user instruction is received and a second user instruction from the user to execute the condensation removal when the temperature information satisfies a predetermined condition.
